8 hours of burn to make a 5 degree temperature rise on the building
no heat loss calc? --- hummmmm
Well at least you can easily track your degree day load over the same period and track your run time to that.
Then -- leave the temp at 60one day -- wire a timer over the stoker to track run time and extrapolate that into the same time of degree load and you can determine if that big a set back on this coal boiler install is worth while. Try a 10 degree set back -- try a 2 degree. Plot each against your degree day weight.
This is for training - Right?
Maybe this will help.http://www.degreedays.net/
